I was doing an onsite with Ilya and the folks at MixRank (in 2012) and talking with the team, and I mentioned something about cryptography and some basic codes that I learned as a child in gifted class. They had no idea what I was talking about - not the codes but "gifted class". I was telling them it was pretty common in public school systems - once a week or a few hours a day where you took advanced topics in another classroom with other kids that had tested into the program. They had no idea.
I started asking the founders if they went to public school. They never had. And then they were curious and started asking the other employees. Not a single one had ever set foot in a public school for elementary, middle, or high school. Then one guy in the back piped up - "you know, I think $devname went to Berkeley."
